Numerical Simulation of the Global Atmosphere

这个项目将研究在南半球观测到的行星波行为的物理机制。重点研究1和2号纬向波的准平稳分量和行分量。这些成分在南半球的春季尤为重要，与北半球的成分有很大的不同。简单的动力学和一般环流模式（UCLA-GCM）将用于调查。将进行敏感性研究，以了解不同强迫机制对行星波产生的影响。这项工作将增强我们对大气环流的基本认识。

This project will investigate the physical mechanisms for the observed behavior of the planetary waves in the Southern Hemisphere. The work will focus on the quasi-stationary and traveling components of zonal wave numbers 1 and 2. These components, which are particularly important during the southern spring, differ significantly from their Northern Hemisphere counterparts. Simple dynamical as well as general circulation models (the UCLA-GCM) will be used in the investigation. Sensitivity studies to understand the influence of different forcing mechanisms on the generation of the planetary waves will be carried out. This work will enhance our basic understanding of the general circulation of the atmosphere.
